Answer:
decreases
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
Global winds such as the jet stream effect weather and climate
Answer:
A) The presence of iron oxides (rust) in sedimentary rock layers that are 2 billion years old.
Explanation:
- Cyanobacteria are aquatic and photosynthetic ,they live in water and manufacture own food releasing oxygen as a by product and in which most living organisms depend on.
- Cyanobacteria are found in the ocean and are believed to be responsible for the formation of the iron oxide found on the sedimentary rocks since they release oxygen as a by product and it is used in the iron oxide formation process below the level of wave disturbance.
